The equation that has no real roots is 3x² + 4√3x + 4.
Option D is the correct answer.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 9 is an equation.
We have,
If the discriminant of the equation is less than zero the equation has no real roots.
Discriminant < 0
D < 0
D = b² - 4ac
Now,
The equation is in the form of ax² + bx + c
x² - 4x + 3√2 = 0
D = (-4)² - 4 x 1 x 3√2 = 16 - 12√2 > 0
x² + 4x - 3√2 = 0
D = 16 + 12√2 > 0
x² - 4x - 3√2 = 0
D = 16 + 12√2 > 0
3x² + 4√3x + 4 = 0
D = 16 - 48 = 32 < 0
Thus,
The equation 3x² + 4√3x + 4 has no real roots.

Answer:
The percentage change each year is 2%
Step-by-step explanation:
Generally, we can have an exponential equation written as;
f(t) = I( 1 + r)^t
where f(t) is the value at a certain time
I is the initial value at t = 0
r is the growth rate
t is the time we are looking at
Thus, we have it that;
1.02 = 1 + r
r = 1.02 -1
r = 0.02
So, let us write 0.02 as a percentage
We have this as 2/100 which is the same as 2%
The percentage change each year is 2%

2. The table below shows the amount that a catering company charges based on the
number of people at an event. Which of the following equations shows the
relationship between c, the amount the company charges based on p, the number of
people at the event?
People (p)
F. c = 16p
25
G. C = 75p + 13
50
Total Charge (c)
$400
$725
$1,050
$1,375
75
H. p = 13c + 75
100
J. c = 13p + 75
Answer:
The answer is j
Step-by-step explanation:
The equations shows the relationship between c and p is p= 13c + 75.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have table which shows amount that a catering company charges based on the number of people at an event.
So, the equation that can framed from the table as
(y- 400)= (725- 400) / (50-25) . (x-25)
y- 400 = (325/ 25) (x-25)
y-400 = 13(x-25)
y-400 = 13x - 325
y = 13x - 325 + 400
y= 13x + 75
or p = 13c+ 75

Hello There!
The area of a triangle can be found using this formula
[tex]A = \frac{1}{2} (a+b)h[/tex]
where a and b = bases and h = height
The trapezoid shown has the following dimensions
top base = 9cm
bottom base = 14 cm
height = 12 cm
slant height = 13 cm
using this information, we plug in the values into the formula
So [tex]A = \frac{1}{2} (9+14)12[/tex]

Is (0, 0) a solution to the equation y = 9x?
(0, 0) is a solution to the equation y = 9x
Given the equation y = 9x, we are to determine whether (0, 0) is a solution to the equation
To do that, we will substitute x = 0 into the expression and determine if the value of y is 0.
If x = 0
y = 9x
y = 9(0)
y = 0
Since the resulting value of y is zero, hence (0, 0) is a solution to the equation y = 9x
